MECHANISM FOR IMPARTING SUCCESSIVF OR ALTERNATING MOVEMl-INTS.

SPECIFICATION forming part of Letters Patent No. 611,501, dated September 27, 1898.

Application filed February 8, 1898. Serial No. 669,012. (No model.)

To ctZZ whom itmay coitccrn:

- Be it known that I, ELISHA MOORE, a subject of the Queen of Great Britain, residing at Meductic, in the county of York and Province of New Brunswick, Canada, have invented certain new and useful Improvements in Mechanism for Imparting Successive or Alternating Movements, of which the following is a specification. i

Th'eobject of my invention is to produce an alternating or reciprocating movement by In said drawings, Figure 1 is an inverted Fig.2 is a plan view of my improvement.

Fig. 3 is a sectional View through the switch-box and a portion of a car with the operating mechanism in position. Figs. 4:, 5, and 6 are detail views of the operating mechanism; Fig. 7 is a per: spective View of the switch-tongue. Fig. 8 is a plan view of a track and switch, showin g the relative position of contact-plate and Fig. 9 is a perspective view of a slight modification. Fig. 10 is a reverse view of the ratchet-wheels and the cooperating dogs. Fig. 11 is a viewof the magnets.

1 represents the main -track rails, 2 the switch-rails, and 3 the car.

1 is the switch-box, located between the rails of the main track at the juncture of the switch, suitably cased with brickwork. 5 is the covering for said box, of suitable material, which is secured in place by means of suitable bolts 6.

7 are integral depending lugs extending from the under side of-the plate 5.

8, 9, and 10 are ratchet-wheels cast integrally and provided with a suitable axis 11 and 12, having the collars 13 and 14. The teeth on wheels8' and 9 are cut so as'to alternate-that is to say, the teeth on wheel 8 al ternate with those on wheel 9. Wheel 10 is formed with twice the number of teeth that wheels 8 and 9 have.

15 are depending lugs integral with the cover 5, between which is pivoted a dog 16, on the top of which is formed a groove 17, in which one end of a pressure-spring 18 is adapted to slide. The other end of thisspring 18 is rigidly secured to the cover 5.

19 is adepending lug on'the bottom of the cover 5.

20 is the switch-tongue, provided at its rear end with a pivot-pin 21, a portion of which,

as at 22, is round in cross-section, while at 23 it is rectangular. The extreme end of the pin isscrew-threaded. The pin 21 is passed through an opening in the cover 5 and the lug 19, the round portion 22 extending a distance equal to the thickness of said cover and lug,the square portion 23 extendin g above the lug.

24 is a cross-arm provided with a rectam gnlar opening adapted to fit over the portion 23 of the pin and secured in place by means of the nut 25. v

26 and 27 are U-shaped springs to one end of each of which is secured a dog 28, from one side of which extends a slotted plate 29. The dogs 28 are adapted,frespectively, to engage the ratchet-wheels 8 and 9, while the slotted plates are adapted, respectively, to engage the axes 11 and 12. 30 are arms bolted or otherwise suitably secured to the other and longer end of the springs 26 and 27, respectively. ,These springs are pivoted to cross-arm 24.; i

31 is an arm pivoted at 32 to the under side of the cover 5, which extends through the U -shaped bracket 33, secured to the cover.

3 1 is a thumb-screw'passing through the yoke of the bracket'and adapted to control the swinging movement of the arm 31.

is a spring one end of which is secured to the cover, while the other end is in engagement With the free end of the arm 31 and adapted to hold said arm normally up against the under side of the cover. 1

36 is a side lug integral with the arm 31, to

of this spring is secured to the arm 31 at 40. This dog 37 is adapted to engage the ratchetwheel 10.

is an armature rigidly-secured to the arm 31. I

51 is the magnet suitably secured in the switch box immediately below the armature 50.

52 are suitable binding-posts, and 53 53" are insulated contact-plates located between the rails of the main track asuitable distance from the switch. An actuating-conductor 59 extends from insulated contact 53 through a source of electricity 59, through magnet 51 and back to contact-plate 53.

54 is a contact-arm hungin suitable brackets under the car 3 and provided with contact-point 55, preferably composed of a roller adapted to contact with the contact-plate 53. 56 is a weight secured to the other end of the contact-arm.

57 is a foot bell-crank lever secured to the platform of a car and connected to the contact-arm by means of a chain or rod 58, as best seen in Fig. 3.

The operation is as follows: The car 3 approaching the switch pressure is applied to the bell-crank lever 57 by the motorman, thus throwing the contact-point down upon the bed of the track, whereupon it engages or makes contact with the contact-plates 53 53, thus establishing a circuit through the wires to the magnets 51, whereupon the armature is attracted toward the magnet and held as long as the circuit is completed, thus drawing down the arm 31, which through dog 37 moves the ratchet-wheel 10 one tooth, the retaining-dog 17 holding the ratchet-wheel after it is moved against backward movement. This movement of the ratchet-wheel 10 carries both of the ratchet-wheels 8 and 9 simul taneously, the dogs 28 slipping over the teeth of the wheels 8 and 9. In this movement one of the dogs 28 slips into engagement with the teeth on the ratchet-wheel 9. The spring-yoke following the inward movement of the tooth pulls the cross-arm 24 through the arm 30,.

thus throwing the switch-tongue over against the rail of the main track, thus opening the switch. If it is desired that the next car pass by the switch on the main track, the contact-point 55 is thrown into engagement with the plate 53, thus establishing the circuit, whereupon the armature is again attracted to the magnets, thus again operating the ratchet-wheels 10, 9, and 8, and the other spring-yoke is thrown into engagement with the teeth of the ratchet-wheel 8, thus turning the cross-arm 24 by the pull on the arm 30 and throwing the switch tongue over, thereby leaving the main track clear. The spring 35 always returns the armature and its carrying-arm 31 back to a'normal position up against the under side of the cover 5.

The ratchets on the ratchet-wheels 8 and 9 are cut so as to alternate with each other, and

the number of teeth as are on the ratchet-.

wheels 8 and 9. Thus when the ratchetwheel 10 is moved one tooth by the dog 37 the ratchet-wheels 8 and 9 are only moved a distance equal to half that between their teeth. As the teeth on these latter Wheels are cut to alternate, it will be seen that only one of the dogs 28 will be in engagement with the alternating teeth at a time-that 'is to say, when the dog 28 on one of the U-shaped springs 27 is in full engagement with a tooth on, say, ratchet-wheel 9 the other dog 28 is not in positive engagement with the teeth on the wheel 8, but is merely in idle contact with the same ready to snap into the next tooth when the armature is next attracted to the magnets. The backward and forward sliding motion of these dogs 28 is guided by means of the slotted plates in engagement with the axes 11 and 12.

From the foregoing it will be seen that by reason of the construction of the ratchetwheels 10, 8, and 9 and the spring-pawls 28 with their connection to the switch-tongue it is only necessary to employ a single magnet to operate the switch. The binding-posts 52 are placed in the switch-box merely for convenience in disconnecting the magnets from the contact-plate 53 and circuit 59.

It will be seen that by reason of the resiliency of the yokes 26 and 27 and their connection through the arms 30 with the switchtongue said tongue can be knocked out by a car going in the opposite direction without operating the train of ratchet-wheels. This obviates the use of certain springs and the necessity of setting the switch each time. p

In Fig. 9 I have shown a slight modification of the yokes, in which 24L is the cross-arm, pivoted as described, from which extend two spring members or yokes 26 27 coiled near their center, as at 62. 63 is a bracket secured to the cover5 by means of suitable bolts and provided with a cross-arm 64, on which the spring-yokes are mounted by means of the coils 62. The operation of this construction is the same as that described in connection with the yokes 26 and 27.
